Methods for dietary fiber, neutral detergent fiber, and nonstarch polysaccharides in relation to animal nutrition.
TLDR
In addition to NDF, new improved methods for total dietary fiber and nonstarch polysaccharides including pectin and beta-glucans now are available and are also of interest in rumen fermentation. Expand
A net carbohydrate and protein system for evaluating cattle diets: II. Carbohydrate and protein availability.
The Cornell Net Carbohydrate and Protein System (CNCPS) has a submodel that predicts rates of feedstuff degradation in the rumen, the passage of undegraded feed to the lower gut, and the amount of MEExpand
Investigation of chromium, cerium and cobalt as markers in digesta. Rate of passage studies.
TLDR
A new liquid marker, cobalt-ethylenediamine tetraacetic acid (EDTA), and two solid markers, chromium (Cr) and cerium (Ce) mordanted plant cell walls, were investigated and Co- EDTA was found to be comparable to Cr-EDTA. Expand
A net carbohydrate and protein system for evaluating cattle diets: I. Ruminal fermentation.
TLDR
The Cornell Net Carbohydrate and Protein System (CNCPS) has a kinetic submodel that predicts ruminal fermentation and the protein-sparing effect of ionophores is accommodated by decreasing the rate of peptide uptake by 34%. Expand
A mechanistic model for predicting the nutrient requirements and feed biological values for sheep.
The Cornell Net Carbohydrate and Protein System (CNCPS), a mechanistic model that predicts nutrient requirements and biological values of feeds for cattle, was modified for use with sheep. PublishedExpand
A net carbohydrate and protein system for evaluating cattle diets: III. Cattle requirements and diet adequacy.
TLDR
The Cornell Net Carbohydrate and Protein System (CNCPS) has equations for predicting nutrient requirements, feed intake, and feed utilization over wide variations in cattle, feed carbohydrate and protein fractions and their digestion and passage rates, and environmental conditions. Expand
Evaluation of a mathematical model of rumen digestion and an in vitro simulation of rumen proteolysis to estimate the rumen-undegraded nitrogen content of feedstuffs.
TLDR
The UDN values estimated from simulated rumen proteolysis and those determined in vivo for twelve mixed diets were in close agreement and can serve as a simple, rapid and sensitive method to estimate UDN in a variety of feedstuffs. Expand
Prediction of ruminal volatile fatty acids and pH within the net carbohydrate and protein system.
TLDR
In a review of literature data, effective NDF (eNDF) provided a better correlation with ruminal pH than forage or NDF, and individual VFA fractions were inadequately predicted. Expand
A Nutritional Explanation for Body-Size Patterns of Ruminant and Nonruminant Herbivores
TLDR
Calculations suggest that sufficient intake of a high-fiber diet cannot be maintained to provide the energy necessary to support larger body sizes, and changing body size is postulated as a mechanism for differentiating the feeding requirements of herbivores. Expand
The chemistry and estimation of fibre.
TLDR
Because of the failure of the crude fibre method to recover indigestible substances, SI;E appears less digestible than crude fibre in significant numbers of cases (Cranipton & >‘laynard, 1938). Expand
